Description

Technical Field

[0001] This utility model relates to the field of oil tank inspection technology, and in particular to an inspection device for oil storage tanks. Background Technology

[0002] As core equipment in the oil storage and transportation process, the quality of the inner wall of oil storage tanks directly affects storage safety and oil quality. During the production and operation of oil storage tanks, the detection of indicators such as inner wall roughness and surface forming defects is crucial. Currently, quality assessment is primarily achieved by scanning the inner wall with equipment such as scanners and combining this with computer-based comparative analysis.

[0003] In Chinese utility model patents, such as CN220418426U, a device for detecting the inner wall surface of an oil storage tank is disclosed. The device uses a hydraulic cylinder to drive a support to raise and lower the scanner, and uses a push rod motor to push the scanner into the tank. With the help of a rotary motor, it can achieve all-round scanning, which solves the problem of adjusting the position of the scanner inside the tank to a certain extent.

[0004] However, this device has obvious limitations when inspecting tanks with special structures where the opening diameter is smaller than the inner diameter: First, the size of the inspection components such as the scanner and push rod is fixed. If it is adapted to the tank opening size, it cannot cover a large inner diameter area after being inserted into the tank, thus limiting the inspection range. If it is adapted to the inner diameter size, it cannot enter through the narrow opening, making inspection impossible. Second, the inspection components can only move axially and have insufficient radial adjustment capability. Even if they are forced to enter the tank, it is difficult to adjust them to a suitable inspection position, which can easily lead to blind spots and affect accuracy. In view of this, this application proposes an inspection device for oil storage tanks. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detection device for oil storage tanks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detection device for an oil storage tank includes a base plate, a side plate fixedly mounted on the top surface of the base plate, a rotary motor mounted on the outer side of the side plate, a turntable mounted on the output shaft of the rotary motor via a coupling, an extension rod mounted on the outer side of the turntable via multiple electric telescopic rods, two threaded sleeves symmetrically slidably connected inside the extension rods via a spacing adjustment mechanism, a connecting rod rotatably connected to the top surface of each of the two threaded sleeves, a lifting plate mounted on the other end of the two connecting rods, and each connecting rod rotatably connected to the lifting plate, an electric linear guide rail fixedly mounted on the top surface of the electric linear guide rail, a sliding seat mounted on the top surface of the sliding seat, a detection head mounted on the top surface of the sliding seat, and a tank body mounted on the top surface of the base plate via a clamping assembly.

[0008] Preferably, the spacing adjustment mechanism includes a square groove, which is opened on the outside of the extension rod, and each threaded sleeve is slidably connected to the square groove. A double-ended screw is rotatably connected inside the square groove, and two threaded sleeves are symmetrically threaded to the outside of the double-ended screw. A drive motor is fixedly installed on the end face of the extension rod away from the side plate, and the output shaft of the drive motor is coaxially connected to the double-ended screw.

[0009] Preferably, the clamping assembly includes a fixed bracket, which is fixedly installed on the top surface of the base plate. A limiting mechanism is installed on the top surface of the fixed bracket, and the limiting mechanism restricts the sliding of the tank. A movable bracket is slidably connected to the outer side of the base plate. The top surfaces of both the fixed bracket and the movable bracket are arc-shaped, and the tank is placed on the top surfaces of the fixed bracket and the movable bracket.

[0010] Preferably, the limiting mechanism includes two fixing plates, which are symmetrically installed on the top surface of the fixing bracket. Each fixing plate has a threaded rod threadedly connected to its outer side. One end of each threaded rod is equipped with a rocker arm, and the other end of each rocker arm is rotatably connected with a rubber pad. Each rubber pad abuts against the outer side of the tank.

[0011] Preferably, a controller is installed on the top surface of the base plate, and an arc-shaped support plate is installed on the top surface of the base plate, with the top surface of the arc-shaped support plate in contact with the outer side of the extension rod.

[0014] 1. This utility model achieves multi-dimensional flexible adjustment of the detection head through devices such as a rotary motor, turntable, electric telescopic rod, extension rod, threaded sleeve, connecting rod, lifting plate, electric linear guide rail, and detection head. The rotary motor drives the detection head to rotate around the tank body, the electric telescopic rod adjusts the horizontal distance, the drive motor drives the double-headed screw to slide the threaded sleeve, the connecting rod realizes the lifting of the lifting plate and the detection head, and the electric linear guide rail drives the detection head to move linearly. Especially for tanks with an opening smaller than the inner diameter, the lifting plate can be retracted to facilitate the entry of the detection head, and then unfolded to adapt to the inner diameter, effectively solving the problems of limited detection range and difficulty in entry.

The fixed bracket in the clamping component provides fixed support, and the movable bracket can slide through universal wheels. The spacing can be adjusted with the telescopic sleeve and connecting rod to adapt to tanks of different lengths. The limiting mechanism on the fixed bracket pushes the rubber pad against the tank by rotating the rocker arm, which not only enhances the fixation stability but also avoids damage to the surface of the tank, ensuring a smooth and reliable testing process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] This utility model provides a technical solution: such as Figure 1-4As shown, a detection device for an oil storage tank includes a base plate 1. A side plate 2 is fixedly installed on the top surface of the base plate 1. A rotary motor 3 is installed on the outer side of the side plate 2. A turntable 10 is installed on the output shaft of the rotary motor 3 via a coupling. An extension rod 12 is installed on the outer side of the turntable 10 via multiple electric telescopic rods 11. Two threaded sleeves 20 are symmetrically slidably connected inside the extension rod 12 via a spacing adjustment mechanism. A connecting rod 22 is rotatably connected to the top surface of each of the two threaded sleeves 20. A lifting mechanism is installed at the other end of the two connecting rods 22. The plate 23 is rotatably connected to each connecting rod 22. An electric linear guide 24 is fixedly installed on the top surface of the lifting plate 23. A sliding seat 25 is installed on the top surface of the electric linear guide 24. A detection head 26 is installed on the top surface of the sliding seat 25. The tank 8 is installed on the top surface of the base plate 1 through a clamping assembly. The electric linear guide 24 has a built-in limit function, which can ensure the stability of the position of the sliding seat 25. The electric linear guide 24 can precisely adjust the position of the detection head 26 to adapt to different positions inside the tank 8.

[0023] It should be noted that by sliding the two threaded sleeves 20 in opposite directions and cooperating with the rotation of the connecting rod 22, the lifting plate 23 can be driven away from the extension rod 12, thereby driving the electric linear guide rail 24 away from the extension rod 12. Therefore, when detecting a tank 8 with an opening diameter smaller than its inner diameter, the lifting plate 23 can first be placed against the extension rod 12 and, as the extension rod 12 moves, the lifting plate 23 and the detection head 26 can enter the tank 8. Then, the lifting plate 23 can be adjusted away from the extension rod 12, so that the detection head 26 can be adapted to the inner diameter length of the tank 8. It should also be noted that the detection logic of the detection head 26 has been described in detail in the comparative document and will not be repeated here.

[0024] Furthermore, the spacing adjustment mechanism includes a square groove 19, which is opened on the outside of the extension rod 12. Each threaded sleeve 20 is slidably connected to the square groove 19. A double-ended screw 21 is rotatably connected inside the square groove 19. Two threaded sleeves 20 are symmetrically threaded to the outside of the double-ended screw 21. A drive motor 27 is fixedly installed on the end face of the extension rod 12 away from the side plate 2. The output shaft of the drive motor 27 is coaxially connected to the double-ended screw 21.

[0025] The square groove 19 can limit and guide the threaded sleeve 20, preventing it from rotating and allowing it to slide linearly.

[0026] Furthermore, the clamping assembly includes a fixed bracket 4, which is fixedly installed on the top surface of the base plate 1. A limiting mechanism is installed on the top surface of the fixed bracket 4, and the limiting mechanism restricts the sliding of the tank 8. A movable bracket 5 is slidably connected to the outer side of the base plate 1. The top surfaces of both the fixed bracket 4 and the movable bracket 5 are arc-shaped, and the tank 8 is placed on the top surfaces of the fixed bracket 4 and the movable bracket 5.

[0027] The fixed bracket 4 is fixed to the base plate 1, and the movable bracket 5 can slide and adjust. The arc-shaped top surfaces of the two fit the contour of the tank 8 to provide support. The limiting mechanism further restricts the sliding of the tank 8. By adjusting the position of the movable bracket 5, it can adapt to tanks 8 of different lengths. The arc design improves the support stability and effectively prevents the tank 8 from shifting during testing, ensuring a smooth testing process.

[0028] Furthermore, the limiting mechanism includes two fixed plates 15, which are symmetrically installed on the top surface of the fixed bracket 4. Each fixed plate 15 has a threaded rod 16 threadedly connected to its outer side. Each threaded rod 16 has a rocker arm 17 installed at one end, and a rubber pad 18 rotatably connected to the other end of each rocker arm 17. Each rubber pad 18 abuts against the outer side of the tank body 8.

[0029] Two fixing plates 15 are symmetrically arranged on the fixing bracket 4. The threaded rod 16 is threadedly engaged with the fixing plate 15. Rotating the rocker arm 17 can push the rubber pad 18 to press against the tank body 8. The rubber pad 18 can both enhance the friction and avoid damaging the surface of the tank body 8.

[0030] Furthermore, a controller 9 is installed on the top surface of the base plate 1, and an arc-shaped support plate 13 is installed on the top surface of the base plate 1. The top surface of the arc-shaped support plate 13 is in contact with the outer side of the extension rod 12. The arc-shaped support plate 13 enhances the running stability of the extension rod 12, prevents it from shifting due to its own weight or external force, and ensures the detection accuracy.

[0031] Furthermore, multiple telescopic sleeves 6 are symmetrically installed on the outer side of the base plate 1. Each telescopic sleeve 6 is slidably connected to a connecting rod 7, and the other end of each connecting rod 7 is fixedly connected to the outer side of the movable bracket 5. Multiple casters 14 are symmetrically installed on the bottom surface of the movable bracket 5. The telescopic sleeves 6 on the outer side of the base plate 1 slide in cooperation with the connecting rods 7, which guides the sliding of the movable bracket 5. The casters 14 at the bottom reduce the moving resistance, ensure that the movable bracket 5 slides smoothly and avoids deviation. The casters 14 make the adjustment process easier. The combination of the two improves the convenience of the device to adapt to tanks 8 of different lengths.

[0032] This utility model provides a detection device for oil storage tanks. The specific working principle is as follows: First, according to the length of the tank 8 to be detected, the movable bracket 5 is pushed. Under the rolling action of the universal wheel 14, the movable bracket 5 slides along the bottom plate 1. The connecting rod 7 slides synchronously in the telescopic sleeve 6 to maintain guidance. After adjusting to the appropriate position, the pushing is stopped.

[0033] Then, place the tank 8 on the arc-shaped top surface of the fixed bracket 4 and the movable bracket 5, rotate the rocker arm 17 on the two fixed plates 15, drive the threaded rod 16 to rotate and move towards the tank 8, so that the rubber pad 18 is tightly against the outside of the tank 8, and the tank 8 is fixed.

[0034] When the tank 8 with an opening diameter smaller than its inner diameter is detected, the drive motor 27 is started by the controller 9, which drives the double-headed screw 21 to rotate, causing the two threaded sleeves 20 to slide in opposite directions. The lifting plate 23 is then driven to fit against the extension rod 12 via the connecting rod 22.

[0035] Next, the electric telescopic rod 11 is activated to push the extension rod 12 into the tank 8. The arc-shaped support plate 13 provides support for the extension rod 12. Then, the threaded sleeve 20 is adjusted in the opposite direction to move the lifting plate 23 away from the extension rod 12. The electric linear guide 24 is activated to drive the sliding seat 25 and the detection head 26 to move. At the same time, the rotary motor 3 is activated to drive the detection head 26 to rotate, so as to achieve comprehensive detection.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
